What are the 2 different kind of t-cells and what is their jobs?

motikmotik

<span>The two different kinds of t-cells are the Helper t-cells and the killer t-cells.
T cells are named T cells after the thymus, an organ situated under the breastbone. They are produced in the bone marrow and later move to the thymus where they mature. Helper T cells have a primary tsak of activating the B cells and killer T cells. The killer T cells are specialized in attacking cells of the body infected by viruses and sometimes also by bacteria. Additionally, they can attack cancer cells.</span>

In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke

lara31 [8.8K]

Answer:

Explanation:

As given,

Allele A for blue anthocynin.

aa for yellow kernel;

at second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are: AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

Recombinant progeny are 169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.

Why have erosion and deposition increased in both of the prairie ecosystems

Ulleksa [173]

Because that ecosystem is covered in rocks and soil fragments. These fragments can be moved by the wind, water or even gravity.

These fragments can lead towards erosion and deposition. That is why people are trying to plant new grass and trees there so it won't get washed away when the next storm hits.

Hope this helped :)
Have a great day

ANEK [815]

There are two main types of research, which could be classified as manipulation and observation. Both types are fundamental in research.

<h3>Empirical research and evolution</h3>

Evolution is the subdiscipline in biology that studies how organisms change to adapt to challenging environmental conditions.

Empirical research refers to any scientific investigation in which conclusions are drawn from empirical evidence.

This type of research (empirical research) is based on observation of the natural world and experimental procedures.
